Application led January 5, 1916. Serial No. 70,425.

To all whom it may concern.'

Be it known that we, JOSEPH H. HAMLIN and JAMES C. BURFORD, citizens of the United' States, and residents of Winston- Salem, in the county of Forsyth and State 0I' North Carolina, have invented a new and useful Improvement in Tires, of which the following is a specification.

Our invention is an improvement 1n tires, for use with motor vehicles, and the invention has for its object to provide a tire of the charactens ecied, capable of attachment to the or inary forms of wheel rim, and of metal properly shaped to resist crushin stress while at the same time the tire is s ciently resilient to counteract shock and jar imparted thereto and to '(prevent the transmlssion ofsuch shock an A' I In the drawings z-Figure 1 1s a slde view of a wheel provided with the improved tire, Fig. 2 is an enlar ed section on the line 2-2 of Fig. 1, and ig. 3 is a sectional view similar to Fig. 2, showing a modified construction;

The present embodiment of the invention is shown in connection with a wheel 1, having a metal rim 2, seated on the peripheryv of the wheel and having flanges 3 at its oppositeuside edges'for a purpose to be presently described. These flanges are' formed by bending the material of the rim at each side thereof over upon the outer face of the rim,

and each of the said flan es 3 is arc-shaped or curved, and arrange with its concave face inward.

The tire is of sheet metal bent into approximately cylindrical form but having a split on the inner side thereof. As shown, the tire 4 is provided at each side of the -split with a rib 5,' and each ofY the ribs is formed in the present instance, by bending the edges of the tire at each side of the split outwardly and then backwardly and inwardly toward the outer face of the tire, and it is then4 bent again outwardly as indicated at 5L parallel with the outer face of the tire. The ribs are roughly triangular in cross section, being of -the same cross sectional shape as. the holding ribs inthe ordinary clencher tire.

In use, the tire is arranged as shown in Figs. 1 and 2, the ribs 5 fitting on the inner sides of the flanges 3, and itwill be noticed jar to thethat that angle of each rib which is outermost is rounded to t the' inner surface of the adjacent flange.

` If desired the tread of the Atire may be reinforced bya strip or band 6 of leather or the like, arranged at theltread. The strip in the present instance is held in close contact with the l.tread of the tire, by means .of rivets 7. These rivets as shown in Fig.

2 are passed from within outwardly and Y each of the openings in the tire for receiving a rivet is tapering or frusto-conical inform. The hea s of therivets areshaped to fit the tapering openings and the outer end of each rivet 1s upset, as shown inl Fig.

2 to prevent disengagement of the tread 6 and to afford a firmer grip for the tire.

vThe upset outer ends of the rivets form rounded beads which extend beyond the 9 at opposite sides of the split aiidncorrev spending to the ribs `5 'of Figs. 1 and 2' \and lthese ribsare engaged on the inner si eiuof the flanges 10y of the rim 11, the said being supported on the wheel 12.

The tire 8 shown in Fig. 3 is not provided with the strip or band of leather, and the metal in this case comes in, direct contact with the.-l ground. It will be obvious that if desired the ribs 9 might be of solid construction or they might be formed in an other convenient manner.

ith the present f orm, of tire there is no possibility of puncture and a puncture would in no manner affect the proper function of the tire, since an air cushion is not 'outer surface of the tread 6, and constitute 'l used. The resiliency of the metal is utilized -V to provide the cushioning action.

ItA will be noticed from an inspection of Fig. 3 that the rib 9 of the said construction has a portion 9a corresponding to the portion 5a of Fig, 2. The arrangement of these portions 5a and 9a provides a cushion,

and as well permits adjustment of the rib 'to the rim. It also protects the side wall of the tire, strengthening and reinforcing, the same at a point where strength and re:

inforcement is needed. It is at this point where the tire is subjected to the heaviest' stress, and by so arranging the rib the rib is adjustable to slight variations in the size of the rims. A

1. A tire'for motor vehicles, comprising a tubular body of annular form and havinge continuons split at its inner'surface between its inner edges and having its Said inner edges bent outwardly to form an integral holding rib at each side of the split terminating in e reinforcement for the respective body side.

2. A tire for motor vehicles, comprising e tubular body of annular form and having a. continuous split atits inner surface end havin integral holding ribs at the sides of the sit, said ribs being formed by bending' the edges ofthe tubular bodyoutwardly come; of this patent my be obtained for ive cante eeen, by ,addressing the Gemmmoner e! intent into the rib formation, the said edges being extended and superposed on the outer surface of the tire for e distance beyond the rib.

8. A tire for motor vehicles, comprising a tubular body of annular form having its inner edges bent to form hollow rim engaging' ribs, said ribs being spaced from one another and provided with extensions projecting along the outer surfaces of the inner portions of the body sides and lengaging the seme for the purpose described.
